EN 10083-2 1C55 Introduce
As EN 10083-2 1C55s are non-alloy, the composition of each grade is very homogeneous. This ensures that the properties of the steel remain consistent throughout the material, regardless of the size or thickness. Furthermore, the steel grades are designed to be versatile, which allows them to be used in a range of different applications.
Smelting temperature:1872°C - 1865°C
Application:Quenched and tempered steel - Part 2: Technical delivery conditions for non-alloy steel
EN 10083-2 1C55 Material Mechanical Properties
Hardness is a measure of a material's resistance to wear, cutting, and indentation. It is expressed in Brinell and Rockwell scales, which measure the depth of an indentation created by a pre-determined loading. The hardness of EN 10083-2 1C55 steel is typically between 50 and 60 Brinell and between 80 and 90 Rockwell.
